Film and flexible packaging

Norner has a development centre for film and flexible packaging with several pilot lines and wide range of testing facilities.

Flexible packaging plays a key role in the food and non-food industries as well as in packaging of industrial goods and chemicals. Norner have long experience in film extrusion and application and polymer development which makes us a good partner for your projects.

Our film extrusion and pilot lines include:

Hosokawa Alpine MDO

An industrial scale MDO pilot line with in-line slitting and corona treating for converting of films from roll to roll with up to 2000mm roll width.


Collin 7 layer

  • 7-layer combined blown and cast film line. It is based on a BL 600 P design, delivered by Collin Lab and Pilot Solutions.
  • The line is composed of seven extruders, all with L/D:30. There are five extruders at 25 mm diameter and two extruders at 30 mm diameter.
  • All seven extruders may be used for both cast and blow film production.
  • Blown films can be produced at a lay-flat of 550 mm and in a thickness ranging from 10 μm to 500 μm, depending on material and process.
  • Cast film is produced via a flat film die width of 550 mm and slot opening of 0.3 to 2 mm. This allows the final thickness of cast films in the range of 10 μm to 2 mm.

Collin blown film

A small scale mono blown film line with 25mm std. screw and 50mm die diameter and four different die gaps possible.

Output up to 8kg/hr bur sample size from <1kg is possible


Plastik Maschinenbau GmbH

Cast mono film line for film and foil of 0,01 - 1mm thickness with a Ø30mm barrier screw and a 400mm wide slot die. Suitable for production of films for testing as well as foil for thermoforming, read more below.

Gel counting

A Collin extrusion line with advanced gel counting system for quality inspection, quantification on cast film.

Prototype production

We can produce film prototypes for further converting or packaging as critical step in innovation projects.

Processing trials

  • Processability and material evaluations
  • Recipe and structure development
  • New polymer grade development and assessments
  • Development of MDOPE films and Mono-PE laminates
  • Quality improvement
  • Small and industrial scale film trials
  • Product and process development
  • Operational excellence
  • Evaluation of recycled materials
  • RecyClass assessment of recyclability


Our blown film lines are well suited for film extrusion with polyolefins and bioplastics. On the cast film line we have experience with a wider selection of thermoplastics.
